This is my favorite movie to come along since Memento. It is labeled as a comedy, but although there are hilarious scenes throughout, much of the movie is very intense, bordering on unpleasant.
Yeah, yeah -- there's the T&A, but there's something more important here. What makes the movie for me, is that it is thoroughly and absolutely realistic. I have known selfish and manipulative people like Kelly (guys as well as girls), and I'm certain you have as well. I suspect that some of the negative opinions of this movie are really people instead mad at the character of Kelly, and that is because at no time while watching it will you realize that these are all actors reciting a script.
The acting is so good that it creates an effective illusion that you are watching it all take place from someone's cell phone. The story is entirely plausible, the drug scenes are realistic, and I can imagine that something like this actually happened, even the part about the cop.
This movie is definitely not for everyone. If you are entertained by the blockbuster special-effects-fantasy-superhero movies that Hollywood manufactures, you may not appreciate a movie in which there are no good guys to root for; a movie with no special effects and no happy ending. No one falls in love and rides off into the sunset as sentimental music swells up on the soundtrack.
I'm amused that the credits list the lead actresses as "cameramen," but even if it wasn't shot entirely on an iPhone, the scenes are effectively done.
If you are not averse to a dose of reality in a movie, here's a slice of not-so-squeaky-clean life among youth in suburbia.
Highly recommended for the cynical.
